The Cup Holder is easily attached to the bicycle thanks to the clever spring steel construction. Open the spring by pressing the rings together, place it on the handlebar and let go. The Cup Holder clamps down on the handlebars and sits firmly in place never losing grip even during rides over bumps and potholes.
The Bookman Cup Holder for bikes can be flipped and used with either the smaller ring or the larger ring depending on cup size. There's also a "storage cube" included in the package which slots into place when not in use to keep everything flat and tidy.
The construction is completely free from screws and glue and the smart clip design does not only make it easy to use, it is also designed for easy disassembly if you would need to recycle the product.
Only suitable for cups not bottles.
Best fit with handlebars with thickness of around 22 mm.
